How many participants correctly identified cards in Peter Wason's 1960s experiments?

Only about 10% of participants correctly identified which cards needed flipping to test the claim in Peter Wason's 1960s experiments. Most selected card 5 instead of the correct pair of D and 7 when viewing abstract symbols.

Who developed natural deduction systems in the 1930s?

Gerhard Gentzen and Stanislaw Jaskowski developed natural deduction systems in the 1930s to simplify proof presentation. Their work avoided complex axiom schemes by including many different inference rules mirroring actual reasoning processes.

Why do humans perform better on content involving human behavior compared to abstract forms?

Special-purpose mechanisms exist for detecting cheating in social exchanges or handling permissions which explain why humans perform better on content involving human behavior. These specialized tools engage cognitive pathways differently than abstract symbols used in formal logic tasks.
